Bug ID 6566086 is fixed in 127111-08 according to the LDom 1.02 release notes. This bug was about VDC I/O blocking and never failing in a guest if it's service domain failed. So with that bug fix it sounds like I/O will no longer block but will timeout at some point.
Is the timeout tunable? Is it simply handled by sd_io_time now? Also, that bug report said that timing out I/O was desirable in cases where a ZFS mirror was used with multiple I/O domains for redundancy in the guest. To what extent is ZFS supported in a guest with virtual devices. When I've tried to create a zpool with VDC disks in a guest I believe I ran into a problem where zpool complained that it couldn't create the EFI label. Should that work? Thanks, Vic
